More than 3,000 people gathered in northern France to mark the centenary of the Battle of Amiens and the start of the Hundred Days Offensive, the final period of the First World War…

His Royal Highness The Duke of Cambridge joined Prime Minister Theresa May at the ceremony in Amiens Cathedral to remember those who fought in the battle.

Two thousand guests watched the service from inside the Cathedral, including hundreds of descendants of those who fought. A further 1,200 members of the public watched from the Cathedral square.

In a speech, HRH The Duke of Cambridge paid tribute to those who served in the battle one hundred years ago and the cooperation between the Allied nations.

Prime Minister Theresa May said: “The Battle of Amiens was the turning point which hastened the final, decisive chapter of the First World War. A hundred years on, today’s ceremony is a fitting moment to remember those who sacrificed their lives, and reflect on our shared past, present and future.”

On 8 August 1918, the Allied armies, made up of British, Australian, Canadian, French and American forces, advanced over seven miles on the first day of the Battle of Amiens, one of the greatest advances of the war.

The battle demonstrated how the Allies had learned lessons from previous campaigns and combined the use of infantry, artillery, tanks and aircraft to devastating effect.

Amiens also marked the start of the Hundred Days Offensive that won the war sooner than had previously been thought possible. The opening day of the battle was described by the German General Erich Ludendorff as the black day of the German Army.

After the ceremony, in a moment that reaffirmed the bonds of friendship and peace between nations, His Royal Highness, the Prime Minister, along with representatives from France, Germany, Australia, Canada, the US and Ireland laid flowers in the Chapel of the Allies in the Cathedral.
